Rinse and drain chickpeas very well and put them in a food processor. Add shredded beets, salt, red pepper powder, and black pepper and gently pulse to combine. The mixture should still be a little bit chunky.
Now, transfer the mixture to a large mixing bowl. Add sauteed onion and garlic, nutritional yeast, ground pumpkin seeds, 2 tablespoons chopped chives, 2 tablespoons chopped parsley, 1 tablespoon chopped basil, rolled oats, and chickpea flour.
Use a spoon or your hands and mix everything until well combined. Taste and adjust seasonings as needed.
Form the mixture into 6 big patties (approximately 9 cm in diameter) or 8-9 smaller ones.
Heat the oil in a non-stick frying pan over medium heat and cook on each side for about 2-3 minutes until golden.
